Bank processing times, probably.
When you create an Openpay plan, Openpay will transfer payment into your business' nominated bank account the next business day. Following this, regular bank processing times apply. Depending on your banking institution, funds are generally available within 1-3 business days. In some instances, such as public holidays, bank transfers may be delayed.
Maybe you've processed a refund recently?
When you process a refund, your business will still hold on to any amount that Openpay has already transferred to you for the purchase. Instead, you will not be paid for future plans until your future plans 'make up' for the refunded amounts that your business has held on to. Once your future plans exceed the total refunded amount, only then will refund information appear in your 'Daily Tax Statement'
Example 1: If you processed a $100 refund and 3 days later, you put through a new plan for $120 - you will receive a statement the following business day with the refund information (showing a net transferred amount of $20).
Example 2: If you processed a $100 refund and 3 days later you processed a new plan for $60 - you won't receive a statement or payment for the 2nd order. (This is because there's $40 left still credited towards Openpay that needs to be 'made up')
Example 3: If you processed a $100 refund and 3 days later you process a new plan for $60 - no statement is provided.
However, after 2 days, you process another plan for $80 - you will receive a statement the following business day with the refund information (showing a net transferred amount of $40).
If you're positive that it's not any of the above...
If your payment is outstanding for more than 3 business days, or your business records don't show any Openpay refunds, please notify your Openpay Account Manager to assist.
